It's important to recognize bootcamp grads for what they are: people who've been coding for 3-4 months max. Many folks expect them to be seasoned devs with 5 yrs experience but they truly are entry-level.
Most people, as I said, are missing motivation, structure, connections and auto-didactic skills to even get to the point of doing Hello World.
[Oh, and if you interviewed someone who'd been to a 4-week (?) bootcamp, that explains why they couldn't do much. Nothing great in life is accomplished by working for 4-weeks.]
